Refinancing

Blend-and-Extend

Porting
Ability to move an existing mortgage to a new property, subject to lender rules and timing.
Readvanceable Mortgage
Combined mortgage and revolving-credit structure that reopens borrowing room as principal is repaid.
Refinance
Mortgage restructuring that changes balance, amortization, or equity access rather than simply renewing the term.
Mortgage Renewal
Process of choosing new mortgage terms at maturity, either with the current lender or a switch.
Renewal Offer
Lender proposal for the next term that should be compared rather than accepted blindly.
Second Mortgage
Additional loan registered behind the first mortgage, often at higher cost and risk.
Mortgage Switch
Transfer of a mortgage to a new lender without the full balance-and-purpose changes of a refinance.
